For daily drivers that don't get the brake fluid flushed often (2 year should be max), then yes. But for enthusiasts who track their cars occasionally, the primary importance is dry boiling point over wet. It takes about 2 years on average for brake fluid to go from "dry" to "wet" (3.7% absorbed moisture), so if we are flushing as often as we should, the wet boiling point hardly matters. This assumes fluid was poured from a freshly opened container and brake bleeding assistance did NOT include a pressure bleeder without a diaphragm.

For information 99.9% of what people will ever need to know about brake fluid, check here: Torque Brake Fluid ABC's

You'll see there that while boiling points are of a primary importance, other factors are also key in choosing the best fluid. My apologies in advance to any chemical engineers reading this as that page is a layman's synopsis, yet a very good one.
